The Cubs needed a right handed hitting outfielder. Junior Lake is the de facto RH OF on the roster, along with super-sub Emilio Bonifacio. When they broke camp, you would think the front office would not be content with its roster.
Injuries spurred the White Sox to troll the waiver wire. The team may have found a gem in Moises Sierra, who was released by the Blue Jays. He was not hitting in Toronto, but Rick Hahn must have seen something in the 25 year old AAAA type player.
Sierra is hitting .364, 1 HR, 2 RBI in 22 ABs for the White Sox. He had a 12 pitch at bat yesterday where he fouled off pitch after pitch until he got a single. That is a good sign of a professional hitter.
Sierra may be only the 5th outfielder/reverse once Adam Eaton returns from the disabled list, but the whole idea of managing a roster is not be static; when needs arise, a general manager must take action to find a solution. Sierra may return to his career form at some time, but there have been cases where a "change of scenery" and new opportunities spark a player to immediate and lasting improvement.
It probably will help that Sierra is playing most every day. The Cubs continue to multi-platoon their position players except for first, short and catcher (the only consistent hitters so far this season).
And the funny thing is that Steve Stone during his broadcasts has only called Sierra "Moises Alou" a couple of times.
