Fatorda (Goa), Mar 11 (IANS): A first-half goal by Sahal Abdul Samad helped Kerala Blasters FC defeat Jamshedpur FC in the first leg of the semi-final of the Indian Super League (ISL) at the PJN Stadium here on Friday.

With a 1-0 victory over Jamshedpur FC, Kerala Blasters inched closer to a place in the ISL final. The second leg, on Thursday (March 15), will be the decider but Kerala will go into the tie with an advantage.

Sahal scored in the 38th minute to hand Kerala the lead and it could have been 2-0 for the yellow shirts had Adrian Luna's free-kick not cannoned off the woodwork.

Kerala's defence was rock-solid too, withstanding the initial threat from Jamshedpur with Marko Leskovic leading from the front.

League Shield winners Jamshedpur looked off-colour upfront with Daniel Chima Chukwu spurning two gilt-edged chances in the first half and Greg Stewart also missing his usual trickery in the final third.

Jamshedpur started on the front foot with Chima missing a golden opportunity to draw first blood early on from close after Pronay Halder headed down a T.P. Rehenesh free-kick from deep inside their own half only for the in-form Nigerian to fire a volley wide.

Chima got another chance to atone for his mistake, this time Halder doing well again to win the ball from Puitea and set the Nigerian up but the seasoned striker shot wide after beating his marker. Meanwhile, it was heartbreak for Seiminlen Doungel as he picked up an injury and had to be replaced with birthday boy Mobashir Rahman.

Mobashir was in the thick of things almost immediately, finding the near post from a Stewart free-kick that was right off the training ground, outfoxing Kerala shirts with a cheeky layoff for an unmarked Mobashir to cross from the right flank but he decided to try his luck himself, to no avail in the end.

For Kerala, Leskovic was on top of his game keeping the defence tight and also making some crucial interceptions as Jamshedpur kept attacking with venom before Kerala scored against the run of play.

Alvaro Vazquez once again underlined his class and silken skill to first spot Sahal making a run and then play a delightful ball over the top to him which Ricky Lallawmawma tried to clear but instead made it easier for Sahal to collect the ball and dink it over an advancing Rehenesh.

The second half got off to a slow start before Adrian Luna's free-kick came off the inside of the post after T.P. Rehenesh got a glove to it just a minute before the hour-mark. At the other end, Ritwik Das, who scored the winner against ATK Mohun Bagan to help his side win the League Shield, sent an effort over the bar after Stewart and substitute Jordan Murray combined well in the final third.

With three minutes left on the clock, Ishan Pandita skewed an effort from close wide.
