9:42pm: Alden Gonzalez of MLB.com adds that Angels pro scouting director Hal Morris was also present for Johnson's start tonight (Twitter link). Johnson fired a gem, allowing just one hit and striking out nine hitters in six innings. Johnson did leave the start early with what he told reporters (including MLB.com's Joe Frisaro) was a cut near his fingernail. He's expected to make his next start.
7:25pm: The Rangers also have a scout in attendance to watch Johnson's start this evening, tweets Evan Grant of the Dallas Morning News.
7:00pm: The Marlins have already traded one starting pitcher (and their second baseman) today, and the Red Sox are hopeful they'll consider moving another. Nick Cafardo of the Boston Globe reports that the Red Sox are scouting Josh Johnson (Twitter link). No deal is close, according to Cafardo.
Johnson, 28, has struggled in 2012, pitching to a 4.35 ERA in 113 2/3 innings. Johnson has a 7.6 K/9, 2.8 BB/9, and 46.5% groundball rate. Both FIP (3.13) and SIERA (3.79) suggest that Johnson has been the victim of some poor luck. The right-hander is in the third year of a four-year, $39MM contract he signed in January of 2010. He's making $13.75MM this season and will be paid the same salary in 2013.
The Red Sox were said to be pursuing Ryan Dempster aggressively at one point, but Boston reportedly turned its interest to Matt Garza. They've also reportedly had internal discussions surrounding Francisco Liriano. MLBTR's Ben Nicholson-Smith recently ran down some other potentially available starters.
