Here are some of today's notable minor moves — a rather interesting group on the whole — all courtesy of Baseball America's Matt Eddy unless otherwise noted:

Catcher Chris Robinson will retire, tweets Chris Cotillo of MLBDailyDish.com. The 29-year-old, who was a 3rd round pick of the Tigers back in 2005, had a chance to see his first MLB action (and hit his first home run) last year with the Padres. At Triple-A with the Pads and Orioles, Robinson put up a .282/.307/.320 line in 255 plate appearances.

At Triple-A with the Pads and Orioles, Robinson put up a .282/.307/.320 line in 255 plate appearances. The Rangers have signed righty Jason Knapp to a minor league deal, tweets Eddy. As MLBTR's Steve Adams recently explained, Knapp is attempting a comeback after washing out of baseball following successive shoulder surgeries. The big hurler was once a top prospect, and headlined the deal that sent Cliff Lee from the Indians to the Phillies. Though he hasn't thrown a professional pitch since 2010, Knapp is just 23 years old and reportedly has managed to build his heater back up into the 90s.

Reliever Pat Egan has signed with the Reds , Eddy tweets. Though he has yet to crack the bigs at age 29, the towering righty has found success in recent seasons at the upper reaches of the minors. In 2013 with the Braves organization, Egan notched a 2.95 ERA in 73 1/3 innings (though he was better at Double-A than Triple-A). And in 2012, he was good for 67 innings of 1.61 ERA ball for the Orioles' top affiliates.

Reliever Juan Morillo has signed a minor league deal with the Orioles , Eduardo Encina of the Baltimore Sun recently reported. The 30-year-old fireballer struggled in four MLB cups of coffee, and washed out of American professional baseball after 2012 as his walk totals reached unsustainable levels. According to Encina, Morillo served as the closer for the Taiwanese EDA Rhinos, during which time his heater registered at a league-record 99.4 mph.

According to Encina, Morillo served as the closer for the Taiwanese EDA Rhinos, during which time his heater registered at a league-record 99.4 mph. The Orioles have also signed lefty Steve Garrison and first baseman Henry Wrigley to minor league deals, tweets Eddy. Garrison, 27, has thrown in just one big league game, and worked 43 2/3 innings of 3.30 ball for the Diamondbacks' Double-A affiliate last year, his first as a reliever. In the process, he boasted significantly higher strikeout totals (10.1 K/9) than he carried as a starter. Wrigley, also 27, spent his entire career in the minors with the Rays before moving to the Rockies in 2013. Previously a solid (if strikeout-prone) hitter with 20-home run power, Wrigley struggled to a .188/.227/.348 line in 119 Double-A plate appearances last year.

Righty Josh Geer has re-signed with the Padres , Eddy tweets. Geer battled back from Stage III melanoma before the 2012 season. Now 30, the RIce University product saw time in the bigs over 2008-09 but has thrown in the upper minors since. Working mostly as a reliever for the first time last year, he threw 104 1/3 innings of 3.54 ERA baseball with 6.9 K/9 against 2.2 BB/9.

Longtime catcher Rob Johnson will attempt to move onto the mound with the Padres organization, Eddie notes in the same tweet. The 31-year-old saw MLB action behind the dish in every season between 2007-13, carrying a lifetime .200/.275/.295 line in the process. Though a surprising number of converted catchers have found success as pitchers, far fewer can say they appeared at both positions at the big league level.

Though a surprising number of converted catchers have found success as pitchers, far fewer can say they appeared at both positions at the big league level. One example that Johnson can hope to emulate is Chris Hatcher, who has seen MLB time as a catcher and pitcher. Hatcher was recently designated by the Marlins and remains in DFA limbo. As MLBTR's DFA Tracker shows, two others join Hatcher in waiting to learn their fates: Henry Rodriguez (Reds) and Jimmy Paredes (Marlins).
