Key

Corner infielders

Mark Trumbo, 1B, Los Angeles Angels of Anaheim

Dynasty players take note: The Halos called up Trumbo, one of their better hitting prospects. He may not play much in September, and there is some doubt about whether his substantial numbers will translate to the bigs.

Luke to regain his force?

This season, the 6-foot-4, 220-pound first baseman batted .301 with 36 homers and 122 RBIs - in the hitter-friendly Pacific Coast League. He batted .291 with a mere 15 homers and 88 RBIs for Double-A Arkansas last year. Note that Trumbo hit .281 with 32 dingers and 93 RBIs between two levels in 2008, however.

The Angels asked him to play some outfield this year, and he'll do so this winter, too. Power and batting average (he whiffs a lot) are question marks. He just wants to find a spot, and given his numbers, maybe you find one.

Outfielders

Ben Revere, OF, Minnesota Twins

Revere, one of the most electrifying prospects in baseball, won't be more than a pinch runner or defensive sub this year, but he's a future star. He has a lifetime minor league OBP of .389 thanks to a keen batting eye and ability to make contact. He stole 36 bases this season and a total of 89 in the previous two. Keep him in mind, especially for 2012, if not 2011.

Jeremy Hermida, OF, Oakland Athletics

The A's brought up repeat offender Hermida (several counts of disappointment) and plugged him into the right-field socket last night. He went 1-for-4 with a walk. His 2007 season (.296, 18 homers, 67 RBIs) seems like a distant memory.

The Boston Red Sox took that chance this past offseason. Short stretches in which he showed some of his promise were, once again, thwarted by injury. The A's are gamblers, and they'll let him earn some time. You never know.

Pitchers

Luke Hochevar, SP, Kansas City Royals

The Royals welcomed Hochevar (elbow) back from the DL on Tuesday, after his absence of nearly three months. The club pitched him and Brian Bannister (shoulder), also back from the DL, in tandem against the Minnesota Twins in order to get them back into the swing. Hochevar went three innings, yielding five hits, three runs and a walk, with three K's.

Hochevar should get a full turn in the rotation next time. He sports a 5.11 ERA and 1.41 WHIP, with 60 strikeouts, in 81 frames this season. The righty still has plenty of promise and was rock solid in several of his starts before the elbow strain. He seeks consistency, but don't sleep on him yet.
