Here are today's minor moves from around the league…
- Longtime starting pitcher Kip Wells has retired, although he's hoping to remain in baseball now that his playing career is over, ESPN New York's Adam Rubin tweets. Wells was released by the Angels in May, and was considering retirement as of early July. The righty pitched parts of 12 seasons, suiting up with the White Sox, Pirates, Rangers, Cardinals, Rockies, Royals, Nationals, Reds and Padres, and posting a 4.71 ERA with 6.5 K/9 and 4.3 BB/9 in 1,338 1/3 career innings.
- The Astros outrighted Hector Ambriz to Triple-A Oklahoma City, according to the International League transactions page. The 29-year-old right-hander was designated for assignment over the weekend after pitching to a 5.70 ERA with 6.7 K/9 and 3.5 BB/9 in 36 1/3 innings for Houston this season.
- The Nationals released catcher Kris Watts, according to Bill Ladson of MLB.com (via Twitter). Watts, 29, hit just .211/.342/.328 in 43 Triple-A games this year. The former 16th-round pick is a career .250/.351/.372 hitter in 2,006 career minor league plate appearances between the Nationals and Pirates organizations.
- The Orioles announced that infielder Alex Liddi cleared waivers and has been outrighted to Triple-A. Liddi was acquired from the Mariners along with a No. 3 international bonus slot for the M's No. 2 int'l slot. Baltimore designated the 25-year-old for assignment last week to make a 40-man roster spot for Chris Dickerson.
- With Liddi in Triple-A Norfolk, there are two players in DFA limbo, according to the MLBTR DFA Tracker – James McDonald of the Pirates and Cody Ransom of the Cubs.
