Mark Trumbo's upside is poking through

Mike Scioscia played a World Series against the Oakland A's when Mark McGwire and Jose Canseco were young. He played with Mike Piazza and managed Vladimir Guerrero and Troy Glaus.

All of which makes the following comment an intriguing one:

"He's got as much raw power as anybody I've seen step in a batter's box," Scioscia said.

He was referring to the Angels' rookie first baseman, Mark Trumbo, who has replaced Kendrys Morales this season and nearly matched his production. Trumbo entered Sunday's game batting .261 with a team-high 13 home runs and 32 RBIs.

And he might be improving in front of everyone's eyes. Trumbo has been more selective at the plate lately and it's helping him. He is riding a seven-game hitting streak and has endured fewer wild swings than the Angels' other first-year players.

"Over the years, I seem to get better, at whatever level I've been at, as the season progresses," Trumbo said.

Trumbo, who grew up 10 minutes from Angel Stadium, started attending games when he was six years old. That year, Tim Salmon won the Rookie of the Year award. No Angel has won it since. Trumbo leads all AL rookies in homers, hits, doubles, runs and total bases. His primary competition for Rookie of the Year honors could come from pitchers, especially Seattle's Michael Pineda.
