In a fairly unsurprising move, the Diamondbacks called up starting pitcher Tyler Skaggs, who will take the mound in the opening contest of today's double-header for Arizona. However, in a slightly more surprising one, outfielder A.J. Pollock was also added to the roster, with Sam Demel - the loser in last night's contest - being returned to Reno. If you've been counting along at home, you'll note this means the D-backs have 26 men on the roster, but that's okay as a change to the rules this year means that teams can have an extra man for a pre-scheduled double-header. Pollock was named as that man, so will likely be returned to the minors after the game.
However, this might also be a precautionary move, coming as the result of Justin Upton having to leave the game in the first inning last night with a tight hamstring. Jack Magruder Tweets that manager Kirk Gibson is "unsure of Upton status today, has not spoken to Upton or training staff yet." I note that Upton is not in the line-up for the opening game, and may or may not be available for the second game, or off the bench in the opener. Pollock was up with the big-league club earlier in the season, when Chris Young was injured, and hit .245 in 21 games for Arizona, with one home-run and five RBI.
