San Francisco Giants 1B Brandon Belt not close to return

San Francisco Giants first baseman Brandon Belt has been on the concussion disabled list since Aug. 8 and has only played seven games since the All-Star break while battling concussion problems.

His return isn’t coming any time soon, as John Shea of the San Francisco Chronicle reported via Twitter that he’s still at least 10 days away from resuming anything but cardiovascular work:

The 26-year-old got off to a terrific start this season, clubbing five home runs in his first eight games.

On April 23, Belt was hitting .299/.327/.563 with seven homers and 13 RBI.

But he was in a nosedive even before breaking his thumb on May 9 and since that hot start, Belt is hitting just .182/.261/.343 in 30 games, with 11 runs, four homers and 11 RBI while posting 33 strikeouts in 111 plate appearances.

In all, he’s at .237/.296/.446 in 51 games, with 11 homers and 24 RBI with 55 whiffs.

It’s not the follow up he expected from a breakout campaign in 2013, when he hit .289/.360/.481 in 150 games with 17 home runs, 39 doubles and 67 RBI.

He finished last season with a flourish, hitting .346/.408/.576 with seven homers in 52 games in August and September, leading to a great deal of optimism coming into 2014.

Instead, it’s been basically a lost year for the former fifth-round draft pick from the University of Texas, who signed on Aug. 13, 2009, and made the opening-day roster for the Giants in 2011.

Belt was ninth in the National League last season with a 142 OPS-plus and was 10th with 60 extra-base hits.
