Mark Reynolds, Baltimore - It seems like ages since Reynolds was a fantasy stud with the Diamondbacks. Can you remember back to 2009 when he posted 44 HRs, 102 RBIs and 24 stolen bases? He's still not stealing bases, but his bat is getting better. He was hitting just .193 at the end of May, but his average is up to .226 (.405 for the last 12 games) and his OPS over the past two weeks is 1.314. Reynolds is available in one out of every five leagues, apparently many fantasy owners didn't have the patience to wait for his return to form.
Dustin Pedroia, Boston - Pedroia struggled at the start of the year, but he's making up for it now. He's raised his average 30 points since the beginning of the month, including 10 extra base hits in 66 at-bats. With the Red Sox offense clicking on all cylinders, Pedroia should easily score 100 runs this season while knocking in around 85.
Justin Upton, Arizona - He's the Upton brother you actually want in your lineup. Justin has been solid all season, but over the past two weeks has raised his production level with an OPS of 1.214. He's putting together a season like the one in 2009 that got fantasy owners excited about his future contributions to your lineup.
Jay Bruce, Cincinnati - Bruce may be the "streakiest" hitter in the major leagues. When he is good, he's very, very good as in May when he batted .342 with 11 home runs and 33 RBIs. On the other hand, in 18 June games, he's batting .238 with an OPS of 0.667 and just one home run. Unfortunately, you can't take him out of your lineup, because he can turn it around at any second.
Pablo Sandoval, San Francisco - The Giants and Sandoval's fantasy owners were all excited when he returned to the field, but the results haven't been what either wanted. Since returning from a broken wrist on June 14th, Sandoval is batting just .207 with no homers and one RBI. Before the injury he was batting .313 with five home runs, 14 RBIs and looked like the guy who carried the Giants offense back in 2009 (.330, 25 HR, 90 RBI). The "2009 guy" will eventually return, but he should be on your bench until you see evidence of the change. In addition, the team has stated that Sandoval won't be helping out with the catching duties, which lowers his fantasy value in case you were thinking of trading for him while his value was low.
Josh Willingham, Oakland - Willingham has been, and is, the subject of trade rumors and it may be effecting his game. Over his last 12 games, we've seen his batting average fall because of an ugly seven-for-45 streak that includes just one extra base hit. He should not be in your lineup and probably not on your roster either.
