7:54pm: It seems that Williamson’s promotion will come with the expectation of regular at-bats. Giants president of baseball operations said prior to tonight’s game that the Giants are “committed” to giving Williamson an opportunity to play every day this time around (Twitter link via Pavlovic).
The San Francisco organization has cycled through seven left fielders already. Gerardo Parra, Yangervis Solarte, Tyler Austin, Mike Gerber, Connor Joe, Michael Reed and Brandon Belt have all seen action at the position. Parra, Solarte, Joe and Reed have all been designated for assignment (with Solarte being the most recent of the bunch, earlier this afternoon). On the whole, Giants left fielders have put together an astonishingly bad .162/.225/.223 batting line through 142 plate appearances.
9:13am: The Giants are slated to bring outfielder Mac Williamson back onto the MLB roster, according to Alex Pavlovic of NBC Sports Bay Area. He’ll join the club in Colorado today after launching three long balls last night in Sacramento.
Williamson was bumped from the 40-man roster late in spring as the Giants reorganized their outfield. He landed at Triple-A after clearing waivers. It was hard to argue with that decision at the time. Williamson had struggled last year after dealing with concussion issues and had never really run with his chances in the big leagues. At 28 years of age and out of options, Williamson ran out of time.
Circumstances have changed in the intervening month. There has been turnover already at the MLB level, in recognition of the fact that the Giants have one of the least-productive outfield units in the game. Williamson, meanwhile, has mashed at Triple-A. We’ve seen this act before, including a torrid stretch last year at the highest level of the minors (and, quite briefly, in the majors). But that doesn’t mean it isn’t intriguing. Through 98 plate appearances, he’s slashing .378/.459/.756 with nine home runs and a 13.3% walk rate.
This move likely would’ve been made sooner but for the fact that Williamson did not have a 40-man roster spot. But there’s not much to lose at this point, given the uninspiring output of several current players and the Giants’ cellar-dwelling status in the NL West.
