Alfonso Soriano, OF, Cubs: He got off to a slow start in Chicago (no homers, one RBI in April), but Soriano has come on strong. He's 14-for-32 (.438) with four homers in his last seven games. Soriano is hitting .309 overall with 15 homers, 51 runs and 10 stolen bases. He's batting .340 with 11 homers in June.
Troy Tulowitzki, SS, Rockies: Colorado's first-year player hit .244 in April but is now showing why many pegged him as a Rookie of the Year candidate going into this season. Tulowitzki is hitting .321 with four homers, seven RBIs and seven runs in his last seven games. He's hitting .275 overall with seven homers, 35 RBIs and 42 runs.
Justin Verlander, SP, Tigers: Last year's American League Rookie of the Year has won four straight starts to improve to 9-2 on the season with a 2.78 ERA. But that's not the best news for fantasy owners. Verlander has struck out 29 batters in his past three starts, an alarming number considering he hadn't stuck out more than eight in any start prior to June 12.
Nick Swisher, 1B/OF, Athletics: He's 3-for-22 (.136) with no homers and one RBI in his last seven games. Swisher is having a good season overall, hitting .281 with 10 homers and 41 RBIs. He hit .254 with 35 homers and 95 RBIs in 2006.
Julio Lugo, SS, Red Sox: Boston's shortstop is 0-for-27 in his last nine games and is batting .191 overall. Lugo has managed to steal 20 bases despite an awful on-base percentage of .256. Red Sox manager Terry Francona has indicated that Alex Cora could see increased time at shortstop.
Homer Bailey, SP, Reds: Cincinnati's highly-touted prospect was pounded for six runs on six hits in 1 2/3 innings in his last start against the Phillies. However, in his previous start, Bailey allowed one run and two hits in seven innings against the A's. Expect more of the same from the 21 year old -- flashes of brilliances but inconsistency the rest of the season.
