Last one and a half year or so
v AUS so far 56, 8, 0 (Series is ongoing and he already has a 50, early to conclude)
V Ind 52, 61, 1, 82 4, 3 (How is this a failure series unless you expect a century game)
v ZIM 5
V BAN 132, 28, 137 (If this shouldn't be counted then don't count the 5 against Zimbabwe either)
V ENG 83, 30, 5, 6, 87, 78 (How is this a failed series!?)
V NZL 50, 38*, 21, 24, 1 (Probably a failed series)
V SLN 134, 0, 29, 48, 20 (Average series)
Before this he had a terrible tour of Australia where he didn't score a single 50 in 5 innings, and a fairly good home series against NZL where he scored 2 fifties in 3 innings
But despite all this I agree that overall Hash isn't as fluent as he was in his hey days, definitely on the decline and may retire after the WC next year.
