Sidelined for most of the exhibition season with tightness in his right quad, Hill returned to duty about a week ago and has been tearing up opposing pitchers.
In Tuesday's 7-4 win over Baltimore, the spunky second baseman went 3-for-4 with two singles and a double, scored twice and drove in three runs. That pushed Hill's average up to .524 (11-for-21) in seven Spring games.
One of Toronto's rising stars, Hill hit 36 homers and drove in 108 runs in 2009, before backtracking in 2010 with a .205 batting average with 26 homers and 68 RBI.
Xavier Nady was 4-for-5 with three singles and a grand slam home run, scoring three times and driving in four runs against the team he played for last year.
Teammate David Winfree went 3-for-6 with two homrs and four RBI and Kelly Johnson added a 3-run shot in addition to his double and two singles in four at-bats.
The Diamondbacks finished last in the NL West in 2010 and are hoping that some of their power strokes translate into wins in 2011.
