JULY 5: The Blue Jays appear to favor Prado over Hill because of the former’s positional flexibility (starts at every infield spot plus left field since 2012), tweets Jon Morosi of FOX Sports.

JULY 4: The Blue Jays are “heavily scouting” Diamondbacks infielders Aaron Hill and Martin Prado, as well as Padres third baseman Chase Headley, ESPN’s Jim Bowden reports (Twitter link). The Jays were known to be interested in Headley, though the two Arizona infielders are new additions to Toronto’s search for help at either second or third base.

The problem with this trio of players, as Bowden observes, is that all three carry large salaries and are in the midst of disappointing seasons. Headley is owed a little over $5MM for the remainder of the year but is a free agent this winter, whereas Hill and Prado are both under contract through 2016.

Hill is owed approximately $29.3MM over the remaining 2.5 years of his deal and is hitting just .248/.285/.368 with six homers through 337 plate appearances this year. The last time Hill hit that poorly was during the 2010-11 seasons when he was, ironically, playing for the Jays. After being dealt to the D’Backs in August 2011, Hill regained his stroke and posted an .860 OPS over 1030 PA in 2012-13.

Prado, meanwhile, is hitting only .268/.313/.360 with three home runs over 351 PA. He has played mostly at his preferred third base spot this year, though he also has a lot of experience as a left fielder or second baseman. Prado is owed around $27.3MM through the 2016 season.

Toronto is known to be looking for help at either second or third base, with the idea that Brett Lawrie (when he returns from the DL) will man the other position. Given Lawrie’s fielding ability at third, Hill would seem like the more natural fit since Prado is much better defensively at third (career 4.4 UZR/150) than at second (-7.9 UZR/150). It’s possible the Jays might also prefer Hill due to his familiarity with playing on the Rogers Centre turf, though that’s just my speculation.
