Toronto claimed 26-year-old Diamondbacks lefthander Bill Murphy on waivers today, using the 40-man roster spot opened up by righthander Casey Janssen’s placement on the 60-day disabled list.

Murphy, a third-round pick by Oakland in 2002 from Cal State Northridge, has been traded three times in his career for veterans, the first time to the Marlins for Mark Redman in December 2003, then to the Dodgers and Diamondbacks on successive days near the 2004 trade deadline.

In three seasons with Triple-A Tucson, Murphy has struggled to a  9-11, 4.67 record in 114 games (39 starts), but has struck out 261 batters in 302 1/3 innings. Unfortunately, he also issued 159 walks and gave up 314 hits, leading to an ugly 1.56 WHIP.

Working mostly out of the pen in ’07, Murphy had his finest season for Tucson, striking out 102 opponents, against just 43 walks, in 100 innings. His 3.68 ERA and 1.36 WHIP were his best marks since his 20-game stint with Double-A Carolina in 2004.
