Readers: "Prospect Transactions" updates you weekly on the most notable moves involving prospects in the Minor Leagues. All comings and goings of MLB.com's top prospects are included and are ordered by organization.
Notes: MLB.com's No. 80 prospect joined Oakland for the second time this season. Straily pitched 6 2/3 innings of three-run ball -- and picked up his second big league win -- against the A.L Wild Card-contending Angels on 9/11. The 23-year-old right-hander, a proud owner of a five-pitch repertoire, gives the Athletics yet another young arm to help them squeeze into the postseason.
Notes: MLB.com's 20th-ranked Phillies prospect finally got the call. Ruf, a 20th-round draftee in 2009, led the Eastern League in games (139), home runs (38), RBIs (104), on-base percentage (.408). Oh, and he ranked second in runs (93), walks (65) and batting average (.317). All impressive marks for the circuit's MVP, even if we are talking about a somewhat-burly 25-year-old first baseman. (In case you hadn't heard, Philadelphia has one of those, only one much older and much more expensive.) So it may be time to wonder if Ruf, with his career .303 average in the batter's box, is simply a right-handed-hitting version of the Cardinals' Matt Adams. Remember, Adams is 24; also weighs 220-plus pounds; was drafted in the 23rd round in 2009; and has a .318 career clip in the box. Adams, however, is viewed as more of a prospect, at sixth overall in St. Louis' system. Maybe it's time Ruf should be viewed through the same prism.
Notes: MLB.com's No. 88 prospect joined Tampa Bay for the second time this season. Archer pitched seven innings of two-run ball against the A.L West division-leading Texas Rangers on 9/8. He remains in search of his first Major League win. The 23-year-old right-hander has a dynamite fastball-slider-changeup repertoire, but it remains to be seen if he will start 2013 in the bigs.
