Buying and selling players can get very frustrating. Sometimes all the stats show that a player will have a good week, but then they do the opposite. Then other stats will show that a player is primed to have a bad week, yet he winds up having his best week of the season. Trying to guess how players will do is unscientific and unpredictable, but it sure is fun. This installment of MLB Buy ‘n Sell features six players who may be wise to move this week. Three of them are at their highest value of the season, while the other three have a fairly low value. There's a chance, although I wish it was actually more than just a guessing game, that the listed players will not perform as they've been doing for the last week or so, and will either perform better or worse, depending on which section they're listed under. Hopefully this week's predictions wind up better than last week's.

Sell:

Jonathan Sánchez (SP - San Francisco Giants) - Sanchez was a promising prospect, but his first two seasons were filled with inconsistency. He would take one step forward and two steps back, giving him ugly numbers. He always did have good stuff though. Now it seems like he's finally gotten the hang of things and has had five starts in a row in which he's gone at least six innings while allowing only two or less runs each time. He is a perfect sell high candidate because he's coming off a terrific week. His stat line for his last week is as follows: 2 wins, 14 IP, 12 K, 1.29 ERA, 1.07 WHIP. Those are fantastic stats, but he has had five good starts in a row. Even the best pitcher in the league is bound to slip up every now and then, therefore there's a chance that Sanchez is "due" for a bad week. Since his value has never been higher this may be the best time to unload him and get another quality player/players in exchange for him.

Johnny Cueto (SP - Cincinnati Reds) - Cueto is a very interesting young player. He was absolutely dominating in his first career starts, but then he fell from grace and was absolutely horrible. This week he started to pitch more like he did at the beginning of the season, plus the Reds' offense seemed to pick it up which helped take pressure off of him. Since May 27 Cueto has a 3-0 record with an ERA of 3.50. He offers a very solid strikeout rate, but he seems to always have a WHIP that's a tad high. As mentioned, he had a very good week and produced the following stat line: 2 wins, 13 IP, 11 K, 3.46 ERA, 1.23 WHIP. He helped fantasy owners out, but because of his early struggles it may be wise to sell him while his value has finally recovered. He seems to be a streaky player, and although he's very talented, it may be wise to get something while you can, just in case.

Michael Young (SS - Texas Rangers) - Young is a phenomenal shortstop. He currently owns a league best 22 game hit streak that has raised his average from .288 to .309. He's also scored 25 runs, hit 3 HR and drove in 13 RBI during that time. He's been a very consistent player, but things may change now. All of a sudden Young has become banged up. He now has a hairline fracture in his left ring finger, plus he's troubled by a sore groan. The fracture isn't much to worry about, yet, but if it somehow gets damaged any further then Young could be in trouble. As for his groan, which can be a nagging injury, it could disrupt his swing and his speed. Young's value is mainly his ability to hit for contact and get on base. The groan injury may compromise that. His stats for the week are very enticing and could help an unwary owner make a deal for him. His stats for the week are as follows: 13/28, 9 runs, 1 HR, 7 RBI, 1 SB, .464 AVG. He's been a very productive player, but his real value has come since he started his hit-streak. He's got two possible injuries that may compromise his main value so it may be wise to get something for him.

Buy:

C.C. Sabathia (SP - Cleveland Indians) - Sabathia has not won a game since May 14. It was an incredible game too in which he threw a complete game shutout. He's lost three of his last four since that game. However, sometimes stats can be misleading. His first loss since his last win was a performance in which he went seven innings, gave up only two runs, and struck out eight. In his next game, a no-decision, he went seven inning, gave up only one run, and struck out five. His last two losses were a bit worse though, but he was able to go eight innings in one and six innings in the other. He didn't exactly implode; he just didn't have luck on his side. Sabathia's main value, aside from wins, has always been his ability to go deep into games while striking people out. His last start is an example of how he still has his "stuff" but hasn't put it all back together again to get a quality outing: 0 win, 1 loss, 6 IP, 8 K, 6.00 ERA, 2.00 WHIP. That may not exactly look great, but he did have eight strikeouts in only six innings. In that game he allowed five runs (four earned) in six innings. His WHIP could have been much worse, plus he had been doing pretty well until he threw one bad pitch that got him knocked out of the game. He has been extremely inconsistent, but some of his losses weren't as bad as they were made out to believe. He could possibly be had from a fantasy owner who's tired of dealing with inconsistency.

Joakim Soria (RP - Kansas City Royals) - Soria has had a rough week against the Yankees. That may be a great thing for fantasy owners in need of saves. Before blowing the game against the Yankees, which I might add was an awesome game; Soria had been 16 for 16 in saves since last year. He has absolutely electric stuff and was a lights-out closer. However, Jorge Posada, Johnny Damon, etc., brought him down to Earth. Now is the time for the suave fantasy owner to sneak in and get a steal on someone who may not be in another owner's good graces. When Soria was a reliever, before becoming a closer, June was his month. In fact, he was perfect in June. His June stat line from last year is as follows: 10 games, 11 IP, 3 hits, 3 BB, 13 K, 0.00 ERA, 0.55 WHIP, .083 BAA. Those numbers are incredible for any reliever, but Soria isn't a normal reliever. He's a closer this year and coming off of his first blown save. A smart owner could throw out the fact that he's part of the Royals and will never get many save chances, but in reality Soria has a very good chance to convert more saves while also providing owners with a fantastic K/9, ERA, and WHIP. He's an extremely talented pitcher, and given the amount of talent he has, this is probably the lowest his value will be this season.

Adam Dunn (LF - Cincinnati Reds) - Every owner gets a fantasy man-crush on certain players. Players that have a lot of ability and talent, but usually aren't worth the same to others as they are to you. Adam Dunn is one of those players that I personally have a fantasy man-crush on, strictly in fantasy baseball that is. He strikes out way too much, his average never gets as high as you would like, and every year he makes a statement about how his goal is to steal 20 bases, yet he's lucky if he winds up with 8 or 9. However, nobody can deny that Adam Dunn is a homerun hitting machine. Who wouldn't love a player who averages around 30% of his hits as homeruns? The answer is someone who hates strikeouts and low batting averages. Dunn has averaged 40 or more homeruns for the last four years and is on pace for another 40 HR season. He's only hitting .243 though and that can absolutely kill fantasy owners. However, sometimes it's just worth the risk. His stats for the week are a great example: 3/19, 3 runs, 2 HR, 5 RBI, 0 SB, .158 AVG. He had recently been on a tear, but slowed down. His off week still resulted in two of his three hits going for homeruns, while he also drove in five runs. His average was horrible, but he's gone through stretches where he belted homeruns on a consistent basis. From May 14 until May 19 he was 7/16, 5 runs, 5 HR, 10 RBI, 3 BB, .438 AVG. He strikes out a ton, he hits for a low average, but he can help carry any team when it comes to hitting homeruns, especially if he goes on another tear like he did a month ago. A smart owner can try their luck by bringing up the low average to an unsuspecting owner. You may just get lucky.
