Frieser gives Tykes win over CoventryDominik Frieser scored the only goal of the game as Barnsley welcomed their fans back to Oakwell with a home win over Coventry City.
Frieser slotted past Simon Moore after being played in by Romal Palmer and the Tykes held out despite some intense pressure from the Sky Blues.
Viktor Gyokeres clipped the crossbar with a first-half effort and following the interval Coventry defender Michael Rose saw a header cleared off the line by Cauley Woodrow.
A foul on Jamie Allen led to Coventry being awarded an added-time penalty, but Brad Collins made a superb save to keep out the spot-kick by Gyokeres.
Barnsley, who had eight players booked, are now unbeaten in seven home league games against Coventry stretching back to 2009, five of them ending in wins.
And the result enabled Markus Schopp to emulate his three predecessors as Tykes boss - Daniel Stendel, Gerhard Struber and Valerien Ismael - by winning his first league match at Oakwell.
Schopp was again without Belgian signings Obbi Oulare and Aaron Leya Iseka, who are still not match fit, and also lost fellow forward Carlton Morris to injury after 33 minutes.
But Frieser found the net five minutes later to the delight of home supporters in the 13,961 crowd, who had earlier marked the death of former skipper and assistant boss Eric Winstanley in May, with a fifth-minute round of applause.
Woodrow glanced a header wide of the target after the break but was then in the right place at the other end to prevent Rose from levelling the scores.
Coventry - managed by former Barnsley boss Mark Robins - continued to press and Collins had to make a flying save to keep out Gustavo Hamer's free-kick.
Robins sent on Jake Clarke-Salter, signed on loan from Chelsea on Friday, as a substitute and his perfectly timed tackle denied Clarke Oduor a chance to put Barnsley out of reach.
It looked like the Sky Blues were going to rescue a point when the referee awarded a penalty following substitute Jordan Williams' tackle on Allen, but they failed to repeat last weekend's stoppage-time goal that beat Nottingham Forest as Collins denied Gyokeres.
Coventry boss Mark Robins told BBC Coventry & Warwickshire:
"I thought we dominated from start to finish, conceded a really poor chance in the first half which ends up in the net.
"Apart from that, they've done nothing and I thought we were outstanding in most areas, but we have to be more clinical in that final third.
"When we've got balls in and around their penalty area, we have to find a pass in the penalty area to make something happen, and be calm in there, and we lacked that a little bit.
"I want us on the front foot and for most of that game, we were."
