The Rockies announced a few roster moves today, recalling right-handed pitchers Justin Lawrence and Antonio Santos, while optioning infielder Rio Ruiz and designating right-hander Chi Chi Gonzalez for assignment.
The Rockies non-tendered Gonzalez in the offseason and then re-signed him on a minor league deal just over a week later. He had his contract at the end of spring training and stayed a part of the staff until the last day of the season. In 24 games this season, 18 of them starts, he has logged 101 2/3 innings with an ERA of 6.46. That may be somewhat inflated by Gonzalez playing his home games in the most hitter-friendly park in the league, but his underlying metrics aren’t much better. His 12.5% strikeout rate is just barely half of the MLB average, which is 23.2%. His 6.3% walk rate is pretty solid though, considering the league average of 8.7%.
Based on that middling production and the fact that he had already been non-tendered by the club once, they were probably heading down the same path this winter. For the club, they decided to just move on now and use the last day of the season to give another look to some younger arms. Lawrence, 26, and Santos, 24, have each logged their fair share of miles shuttling between MLB and Triple-A this season, each one having been optioned six times. Lawrence has a bloated 8.64 ERA over 16 2/3 MLB innings this season, but a much more palatable 4.73 ERA in 32 1/3 Triple-A innings. Santos is somehow the reverse, with an MLB ERA of 4.76 in 11 1.3 innings but a Triple-A ERA of 7.94 in 45 1/3 innings.
