The Dodgers announced today that they have sent Ramon Troncoso back to Albuquerque:

Los Angeles Dodgers relief pitcher Ramon Troncoso was optioned to Albuquerque today, creating an opening for fellow reliever Ronald Belisario to return to the active roster from the restricted list Tuesday.

Troncoso pitched 2 1/3 shutout innings over two games since being recalled from Triple A on Aug. 3, when Jeff Weaver was placed on the disabled list. Troncoso — like Belisario, a mainstay of the Dodgers’ bullpen in 2009 — has a 4.85 ERA in 39 innings this season.

The Dodgers, who were off Monday, did not immediately confirm that Belisario would be activated before Tuesday’s game in Philadelphia. However, Dodger manager Joe Torre said over the weekend that Belisario, who made rehabilitation appearances for Class-A Inland Empire on Saturday and Sunday, was close to a return.

Belisario has not pitched for the Dodgers since July 5. He was placed on MLB’s restricted list effective two days later, for reasons still not publicly disclosed. Belisario, who resumed workouts two weeks ago, has a 3.79 ERA in 35 2/3 innings for the Dodgers.

Belisario’s 2010 season also began on the restricted list, after visa problems delayed his spring training arrival. Belisario had a 2.04 ERA in 70 2/3 innings last season.

What’s interesting to me is that the Dodger bullpen suddenly seems so deep that it could part with Troncoso even though he had not been scored upon since his return — and that’s with Weaver still sidelined. The offense, certainly, remains a different story.

After Brandon Morrow threw a 17-strikeout one-hitter Sunday, Stat of the Day made a list of all the pitchers under age 26 since 1920 who had thrown one-hitters while striking out at least 10, within their first 160 career games.

Two Dodgers are on this quirky list. Sandy Koufax is one. If you can guess the other without looking, I’ll be really impressed. Name the non-Koufax Dodger under the age of 26 who struck out at least 10 batters in a one-hitter. It came in the pitcher’s 22nd career game.
