Zimbabwe 267 and 38 for 3 (Bennett 15*, Humphreys 1-4, McCarthy 1-14) need another 254 runs to beat Ireland 260 and 298 (Balbirnie 66 Tucker 58, Ngarava 4-55, Gwandu 2-28, Madhevere 2-48)
Ireland are well placed to complete a hat-trick of Test wins after setting Zimbabwe a target of 292 and reducing them to 38 for 3 at stumps. Andy Balbirnie and Lorcan Tucker struck fifties with contributions all the way down the order helping them take control of the game in Bulawayo.
Richard Ngarava, who took three of the last four wickets to fall, finished with a four-four; but it was the part-time spin of Wessly Madhevere that removed Balbirnie and Andy McBrine - Ireland's top scorers of the second and first innings respectively.
Balbinie started the day with Campher and the duo grew their partnership from 37 to 75 with relative ease. There were nicks - like in the first over of the day - that weren't carrying, the funky fields from Jonathan Campbell weren't forcing batters into shots, and Blessing Muzarababi's five-over opening spell was seen off without loss.
Campher picked up two boundaries off Trevor Gwandu - a stylish whip and a technically sound straight drive - before the bowler found his length to quieten the batter and then nick him off after drinks.
Ireland were 121 for 2 - a great entry point for Harry Tector, who got off a pair and got into his innings cautiously. Balbirnie, meanwhile, coasted along at his own pace to bring up a 106-ball fifty. He nearly dragged one on in the 34th over and weathered an examination by spin to take the lead up to 142 at lunch.
The spin of Campbell and Madhevere took hold after the break; first with the former ripping a legbreak to beat Tector's full-faced block and trap him lbw, then the latter ripping an offbreak to beat Balbirnie's flick to do the same.
Paul Stirling, who was more generous in peppering attack with defence, swept Madhevere over square leg for six and heaved Campbell wide of mid-on for four. He was out caught down leg, trying to pull Muzarabani fine, but was unhappy with the decision.
Tucker was off to a quick start too. He swept Campbell for two fours in the 59th over and consolidated after Stirling fell. He stitched handy 39-run and 23-run stands with McBrine and Mark Adair as Zimbabwe kept at it with spin before the second new ball became available.
McBrine was troubled by Madhevere, who beat his outside edge first (71st over) then snagged it for Nick Welch at slip to complete the catch (75th). Adair slogged a six off Madhevere and was comfortable against the old ball but edged two of the five he faced against the new ball, the second of which went to Takudzwanashe Kaitano's hands at slip. It left Ireland 261 for 7 at tea.
Ngarava toyed with Barry McCarthy before knocking him over with a well-executed slower ball. Gwandu got a shortish ball to skid past Craig Young's defences but that inconsistent bounce might be something that comes back to haunt Zimbabwe soon. Tucker and Matthew Humphreys, the last pair to bat, did run and walk along the danger area of the pitch a couple of times, but they were not pulled up by the umpires.
Tucker brought up fifty by pulling Ngarava and then flayed him over extra cover. But when he charged and tried to slap him over the off side two overs later, the top edge took the ball straight to cover. Ireland, who had conceded a seven-run lead, were all out for 298.
Zimbabwe came out to bat with an hour left in the day and McCarthy induced an edge from Ben Curran in the sixth over to have the opener caught behind for the second time in the game. A length ball that went away was set up by a few coming in to find the edge.
Adair ended Kaitano's promising start, which included three boundaries, with another set-up. This time with outswingers before slowing up a fullish ball to beat the inside edge and hit the stumps.
Humphreys trapped Welch, Zimbabwe's top scorer in the first innings, lbw with an arm ball that beat his flick. It brought Gwandu for nightwatch duty and he survived 12 balls to stumps. Brian Bennett, in at No. 4, had a close shave in the final over.
The highest successful chase in the fourth innings in a Test hosted by Zimbabwe is 192. So, the hosts will need to break that record if they are to win.
